Maybe things get better when using (more up-to-date) gtf instead of cvt. # gtf 3840 2160 60 # 3840x2160 @ 60.00 Hz (GTF) hsync: 134.10 kHz; pclk: 712.34 MHz Modeline "3840x2160_60.00" 712.34 3840 4152 4576 5312 2160 2161 2164 2235 -HSync +Vsync If it works with Fedora, they most likely use another amdgpu kernel module and/or they use different firmware files for Picasso ... Anyway, please reboot with boot option "drm.debug=0x06" and attach the output of "dmesg". Thanks. -- You are receiving this mail because: You are on the CC list for the bug.

Not sure about KDE, but GNOME3 supports Wayland. But then you would need to install also the GNOME pattern and gdm package and select "GNOME" session in gdm-greeter. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1165977 http://bugzilla.opensuse.org/show_bug.cgi?id=1165977#c12 --- Comment #12 from Stefan Dirsch --- Yeah! That's it! Can HDMI 1.4 4k? This is sufficient for a resolution of 3840 x 2160 pixels with a maximum repetition rate of 30 Hz and corresponds to the HDMI specification 1.4. ... That's why HDMI 2.0 defines a maximum bandwidth of 18 GBit / s. This allows Ultra-HD signals to be transmitted with a repetition rate of up to 60 Hz. -- You are receiving this mail because: You are on the CC list for the bug.
